An Mcs Basic-52 Sbc Using Anything But An 8052ah-Basic, Hyunyeop Lee

Theses

This thesis exploits the ways to develop a new MCS BASIC-52 SBC using anything but an 8052AH-BASIC microcontroller. The 8052AH-BASIC based SBC offers short development time and low system cost; it is advantageous for numerous applications especially in the instrumentation, measurement and process control. However, the 8052AH-BASIC is no longer officially supported by INTEL and could disappear. Also, this SBC is not adequate for applications where power consumption is an important factor because the 8052AH-BASIC, a MOS product, draws a considerable amount of current.

To solve these problems we demonstrate how the 8052AH-BASIC can be replaced by any of a …

The Legal Studies Of Women Employees, Yi-Ling Lin

Theses

Discrimination against women in the workplace has always existed, but because few women in the United stated worked until the Second World War, it was not regarded as a major issue before then. Although Title VII of the Civil Rights Act of 1964 forbids employer and union discrimination based on race, color, religion, sex or national origin, many available studies still showed that most women experienced discrimination in employment, especially in salary and promotion. In addition, there were a growing number of cases of sexual harassment in the workplace. This study was concerned with the implementation and effectiveness of legislation …

Japanese Management Techniques And The Civil Rights Act Of 1964 (Title Vii), Doris S. Mao

Theses

Japanese management techniques have been praised for its high efficiency and quality output. However, when these same techniques are transplanted in the United States, the results have been less than desirable. This thesis will investigate how the nature of the Japanese management system lends itself to employment discriminations which have resulted in court cases against Japanese firms in US.

The thesis will firstly identify the unique characteristics of Japanese management techniques and the reasons behind the efficient operations of Japanese firms. Since the Japanese management system is based on a paternal concept which identifies the corporation as the "second family", …

Trellis Coded Tamed Frequency Modulation In Rayleigh Fading Channels, Kiran R. Patel

Theses

It is usually difficult to reduce the effects of channel impairements on transmitted information. A fading channel is one such media in which digital communications system operates. A signal is subject to distortion in amplitude and phase when propagating towards the receiver. This puts constraint in required SNR at the receiver, for given performance. Various modulation/coding and demodulation/decoding techniques are employed to lessen the effects of fading. Bit error rate is a performance parameter that sets the criteria for signal design, system architecture and performance.

Here, a slow Rayleigh fading channel with three propagation paths possesing a scattering function of …

Theses

The comparative performance of several Lapped Orthogonal Transforms(LOTs) [1][2][3][12] is studied in this thesis .

Impacts Of Treated Municipal Waste-Waters On Development And Growth Of Hudson-Raritan Estuary Fishes, Chien-Min Chen

Theses

The Hudson—Raritan Estuary, known as one of the worst polluted estuaries in the world, receives pollutants from many point sources. Treated municipal wastewater (TMW) counts for 13% of its total freshwater input and more than 98% of the chemicals classified as priority pollutants been infused. Because of the complexity of the input, treatment facilities cannot remove toxicants efficiently. In addition, generation of new compounds by water treatment such as chlorination occurs. Batch-to-batch variability in the chemistry of this effluent was reflected in the early life stage toxicity bioassays using mummichog (Fundulus heteroclitus) and winter flounder (Pseudopleuronectes americanus) embryos.

Interconnection Of X.25 Networks, Syed Ayaz Qutubuddin Ahmed

Theses

The purpose of this work was to investigate the performance of two interconnected X.25 networks via CCITT internet protocol X.75. Since internet protocol X.75 follow the same flow approach as X.25, we are allowed to model the acknowledgement queue in such a way that this queue provides a feed back path from destination to the source queue. Thus we are able to model our interconnected network as a closed queueing network with limited number of packets in transit within the network. Mean Value Analysis with Blocking (MVA) algorithm was applied to obtain the performance characteristics as the resources available were …

Performance Evaluation And Comparison Of Ordinary, Adaptive And Exhaustive Service In The Token Ring Network, Darshakkumar J. Patel

Theses

In the token ring network different types of services gives different delay characteristics. Results to date have shown that in asymmetric traffic, exhaustive service gives more delay to lightly loaded stations where ordinary service wastes time in circulating the token after each transmission. In general, there is a need for more efficient service, which is compromised between ordinary and exhaustive service.

Ordinary and exhaustive service are analyzed in this thesis, and a new service, adaptive service, is proposed. By using timer and counter, adaptive service dynamically changes token holding time at the station. Different types of delay characteristics are derived …

Teaching Mechanical Design Using The Axiomatic Approach, Lisa E. Hailey

Theses

Many authors on the subject of design state that it cannot be taught, it must be learned through experience. This thesis offers a method in which design can be taught to senior mechanical engineering students. The axiomatic approach to design, authored by Dr. Nam P. Suh of the Massachusetts Institute of Technology, states that all good designs follow two axioms, the independence axiom and the information axiom. By teaching students to use these axioms, and the corollaries and theorems derived from the axioms, educators can teach students the basic concepts of good design.

To show how this approach can be …

Non-Parametric Dominant Point Detection Algorithms, Kuo-Wei Huang

Theses

Dominant point detection is one of the most important preprocessing steps for landmark-based shape recognition and point-based motion estimation. Two new methods for detecting dominant points are presented. Both methods do not require any input parameter and the dominant points obtained by these methods remain relatively the same even when the object curve is scaled or rotated.

In the first method, for each boundary point, a support region is assigned to the point based on its local properties. Each point is then smoothed by a Gaussian filter with a width proportional to its determined support region. A significance measure for …

Evaluating The Feasibility Of A Vendor Certification Program For A Mid-Sized Pharmaceutical Company, Clarice P. Johnson

Theses

To compete effectively in the global market-place of the 1990's, manufacturers and suppliers must give up the orthodox practices of the past and create more innovative, quality oriented partnerships. One way to do this is through vendor certification.

The implementation process is examined with particular emphasis upon total management involvement and commitment. A case study approach utilizes a literature search, questionnaires from a limited number of pharmaceutical companies in New Jersey, and questionnaires from primary and secondary component suppliers.
